Product Description

Dow Froth Pak 650

Class A fire rated spray foam insulation kits are complete portable two part polyurethane spray foam systems. FROTH-PAK™ polyurethane foam is a two-component, quick cure, closed cell foam that fills cavities, cracks and expansion joints for insulation and air sealing. Air infiltration accounts for 25%-40% of a home’s energy loss, FROTH-PAK™ stops that energy loss. FROTH-PAK™ Foam Insulation kits can be used to insulate stud wall cavities up to 2" thick, cold floors above unheated areas, crawl spaces, attic walls, and ceilings when covered with a code-approved barrier. The kit can be restarted and reused for up to 30 days after first startup. The Froth Pak 650 kit yields up to 650 board feet of foam.

Chemical curing allows 2 part polyurethane foam to be dispensed, expand, and become tack free in seconds. Foam will skin over in 30 to 40 seconds. Reentry to spray area can be made in 1 hour without respirator. Dow Froth Pak 650 is great for bigger jobs; yield is 650 board ft.

Please make sure that both tanks are opened fully and that there are no restrictions in the feed lines. An improper mixture will cause "off ratio" foam. To see what this looks like check out our video "How to tell Good from Bad"

Froth 650 review

Posted by Unknown on Oct 24th 2016

The company hustled to get me the product the next business day, much appreciated (though FedEx tried to sabotage the delivery). Application went fine though spraying up to coat the underfloor of a crawl space is not so much fun. Wear your bunny suit and respirator!

Foam-Pak 620

Posted by Ged on Oct 11th 2013

Product was delivered 2 days after order was placed,exceptional. I used this to insulate a sub floor resting on a concrete base and theFoam-Pak 620 fullfilled this need. It was easy to use carfully following the instructions. I used up the entire contents in one go so cannot comment on storage and re-use. One down side is that it did no go as far as I expected. The 620 board feet (1.4 cu m)listed is theoretical in ideal lab conditions. I would like to know what the practical volume usage is.

good product.

had a small problem with the left hose at the sprayer that seeped some material out. wasn't a big deal though. product sprays and covers well. make sure they are warm like the instructions explain or inconsistent coverage. warmed mine up and worked great. once applied, this product is amazing, like most any spray foam.

sprays beautifully

and besides that it is easy to use--you really have to plan what your doing so you don't have to change nozzles all the time

Froth-Pak 620 review

Posted by Unknown on Mar 15th 2013

I was satisfied with how the Froth-Pak went on. I initially heated the tanks up to 80 degrees and kept them around 75. I was able to do just under 500 square feet. Most spots at an inch thick while other places thicker. I applied it in on my basement walls behind a studded wall. One thing I will do differntly next time is use the "spot" tip to apply the foam behind the studs (~3/4" space) first and then go back through and use the fan tip to fill the spaces between each stud.
